Can you see what's the matter?

There is a folk song below sang by Anna Russel, where we can see one of the characteristic problems of our time in the medical model of mental illness. Let me see if you'll get it.

"I went to my psychiatrist to be psychoanalyzed
To find out why I killed the cat and blacked my husband's eyes.
He laid me on a downy couch to see what he could find,
And here is what he dredged up from my subconscious mind:
When I was one, my mommie hid my dolly in a trunk,
And so it follows naturally that I am always drunk.
When I was two, I saw my father kiss the maid one day,
And that is why I suffer now from kleptomania.
At three, I had the feeling of ambivalence towards my brothers,
And so it follows naturally I poison all my lovers.
But I am happy; now I've learned the lesson this has taught;
That everything I do that's wrong is someone else's fault."
